I really don't see how anyone in their hierarchy thought this was a good idea.
There are at least 3 other competitors that moreorless work better than plex already does, without even having a subscription.
I'm amazed they decided to go this route, especially when migrating is as simple as uninstall plex, install competitor of choice(like jellyfin), and then just specify media locations.
the only real annoying part is remaking user accounts and losing watch progress/history, but there is usually a migration tool for that
